We examined densities of endophytic fungi and their associations with performance of Eriocrania leaf-mining moth larvae on white birch (Betula pubescens) and silver birch (B. pendula) around a large copper±nickel smelter in SW Finland. The analysis is based on 2-year data collected from sites distributed along the pollution gradient from 0 to 10.8 km from the smelter. Endophyte densities were l...

On the basis of qualitative and quantitative analysis with liquid chromatography--electrospray ionisation mass spectrometry, the foliage of dwarf birch (Betula nana L.), silver birch (B. pendula Roth) and mountain birch (B. pubescens ssp. czerepanovii (Orlova) Hämet-Ahti) were found, for the first time, to contain the same individual HTs that were described earlier for white birch (B. pubescens...

During the last two decades, various medicinal plants have been studied for their possible antimicrobial activity to discover new antimicrobial agents capable of resolving problems such as the development of drug resistance in pathogenic microorganisms as well as the side effects of some present antibiotics. In this study, the antibacterial activity of methanolic extract of T. pubescens (rich i...

This study aimed to isolate bacterial neuraminidase (BNA) inhibitory O-methylated quercetin derivatives from the aerial parts of S. pubescens. All isolated compounds were identified as (1–4), which exhibited be noncompetitive inhibitors against BNA, with IC50 ranging 14.0 84.1 μM. The responsible (1–4) showed a significant correlation between BNA effects and number O-methyl groups on quercetin;...

Depletion of natural resources has become a major concern in today’s modern industrialized world centering much attention on sustainability of the built environment and sustainable alternatives to current development and construction practices. In the green building community, strong interest lies in natural and renewable building materials that can be used in structural applications. Just such...

Preface, p. vii Any reasonable logical system can be naturally translated into many-sorted first-order logic; thus many-sorted first-order logic is a universal logic. Since many-sorted logic can be translated into single-sorted first-order logic the latter is also universal. However, as will be seen in the course of this book, many-sorted logic faithfully interprets the semantics of the object ...

In contrast to plant-animal interactions, the conceptual framework regarding the impact of secondary metabolites in mediating plant-plant interference is currently less well defined. Here, we address hypotheses about the role of chemically-mediated plant-plant interference (i.e., allelopathy) as a driver of Mediterranean forest dynamics. Growth and defense abilities of a pioneer (Pinus halepens...

BACKGROUND There is a need to develop potential new therapies for the management of diabetes and hypertension. Australian medicinal plants collected from the Kuuku I'yu (Northern Kaanju) homelands, Cape York Peninsula, Queensland, Australia were investigated to determine their therapeutic potential. Extracts were tested for inhibition of protein glycation and key enzymes relevant to the managem...

Trametes is a cosmopolitan genus of white rot polypores, including the "turkey tail" fungus, T. versicolor. Although Trametes is one of the most familiar genera of polypores, its species-level taxonomy is unsettled. The ITS region is the most commonly used molecular marker for species delimitation in fungi, but it has been shown to have a low molecular variation in Trametes resulting in poorly ...

Bamboo (Phyllostachys pubescens) expansion into adjacent forests is a widespread phenomenon in subtropical regions, and it has greatly changed the dominance hierarchy from trees to bamboos. This process may be accompanied by changes in productivity, nutrients accumulation and biogeochemical cycles. We compared the net primary production (NPP) and major pools and fluxes of nitrogen (N) in bamboo...
